The taste of water is impacted heavily by softening. Hard tap water makes cleaning more difficult and more dependent on soaps and synthetic detergents. Scaling in boilers and teakettles comes from hard water. But hard water does not pose any danger to your health: According to the U.S. National Research Council, the magnesium and calcium in hard water can actually contribute to your daily dietary requirements.

Hardness is the concentration of calcium and magnesium in the water. Hardness can be calculated with this formula (calcium and magnesium should be measured in milligrams per liter): HARDNESS = (calcium x 2.5) + (magnesium x 4)
